Quote - ErickL88, in my experience, it doesn't matter as long as it's not null...

I can't be 100% sure about this as I don't have access to Pose2Lux to check, but I'm pretty sure I've used the 'null' material on emitters in order to have just the texture-based light but not the geometry. I think I used this on candle flames, for example.

Maybe my memory is playing tricks on me though!
